The interior of the light sensor adopts the digital environment light intensity sensor with the highest sensitivity in current light collection, and has many advantages such as high sensitivity and rapid response. Close to the visual sensitivity of the spectral sensitivity characteristics, the peak sensitivity of the typical wavelength: 560nm, affected by the infrared light is very small. With the high-precision analog circuits and program processing, the light curve is corrected accurately. Makes it possible to output light values ​​very accurately.
The sensor has a 50Hz/60Hz frequency debounce function for stable measurement. Through the filter visible light irradiation to the imported photodiode, photodiode according to the size of the visible light into electrical signals, the electrical signal into the microcontroller system, the microcontroller system according to the temperature sensing circuit, the collected optical signal temperature compensation. The product supports the Modbus-RTU protocol format and provides a variety of analog transmissions for the user to choose.

The bluetooth headsets are to apply Bluetooth technology to the hands-free headset, so that users can avoid the annoying wires and easily to talk in various ways. With Bluetooth headset, you can write EMAIL while talking on the phone, you can talk while driving, you can call while doing housework, no more annoying wires!
Advantages:
1: Bluetooth headsets generally has a standby time about 100 hours or more, talking time is about 5 hours or more . It can avoid the trouble of charging constantly, and it is especially convenient to carry.
2: Using Bluetooth headset is very "healthy". The electromagnetic wave of the Bluetooth headset is much lower than that of the mobile phone. When you talk on the phone, just put the mobile phone in your briefcase or in your pocket, put on the headset and talk easily, neither need to raise your hand. It can also effectively reduce the impact of electromagnetic waves on the human body.
